We can already grow brain organoids cheaply and easily enough to be a YouTuber's long-running series, so even if biological somehow gets cheaper than silicon, it still isn't going to be a revived complete human brain from someone who died 50 years earlier and probably retired 20 years before that.

I mean, imagine someone who got themselves cryonically preserved in 1976 getting either revived or uploaded today: what job would they be able to get? Almost no office job is the same now as then; manufacturing involves very different tools and a lot of CNC and robotic arms; agriculture is only getting more automated and we've had cow-milking robots for 20-30 years; cars may have changed the least in usage if not safety, performance, and power source; I suppose that leaves gardening… well, except for robot lawnmowers, anyone who can hire a gardener can probably afford a robo-mower?
